Terabytes of system memory. Samsung has unveiled the all-new CXL Memory Expander, a device that fuses DDR5 with Compute Express Link, an interconnect built on a PCIe 5.0 foundation, giving a preview of what lies ahead for tomorrow's gaming PCs.

Compute Express Link is supported by the entire technology industry, including Intel, ARM Nvidia, Arm, Micron, Samsung, Seagate, Sony, WD, SK Hynix, Microsoft...... and others, is a new interconnect standard supported by the entire technology industry; most major high-tech companies, including those most involved in PC gaming, are participating in CXL.

It is, in effect, a way for devices to share and access resources over a fast, wide memory interconnect, improving performance and efficiency. built using the underlying technology introduced in PCIe 5.0, CXL goes a bit further across three major protocols CXL spans three major protocols: IO, cache, and memory, all of which allow components of heterogeneous computer systems to talk to each other and share large memory pools from devices such as this Samsung CXL Memory Expander to help them share a large memory pool.

Samsung's CXL-based modules are intended for data centers, as over-the-top memory devices often are. Samsung also brings additional controller and software technology to the module that allows it to serve as the primary memory pool for the system.

Dr. Debendra Das Sharma of Intel stated in a Samsung press release that "CXL memory is expected to expand memory utilization to new levels," and that Intel intends to help develop a more robust ecosystem around this technology.

AMD is also getting into memory bandwidth as a priority; AMD's Dan McNamara said, "Memory research is a key element to unlocking this performance, and we are excited to work with Samsung to deliver advanced interconnect technology to our data center customers."

McNamara added, "We are very excited to be working with Samsung to provide advanced interconnect technology to our data center customers.

There are far fewer opportunities for the humble gaming PC to use more than a terabyte of memory, but that does not necessarily mean that the PC memory sector is likely to change more dramatically. Gaming consoles, and to some extent PCs, are starting to wake up to the bandwidth issue; I/O plays a big role in the PlayStation 5 and Xbox Series X architectures, and it won't be long before PCs can also taste more extensive bandwidth and more effective memory utilization It won't be long before PCs can enjoy wider bandwidth and more effective memory utilization.

Perhaps terabytes of DDR5 are a bit out of the question, or more accurately, out of budget, for most PC gamers, but DDR5 and PCIe 5.0 will be coming to PCs later this year with Intel Alder Lake. are already in production.
